I've been using Windows for quite a while, but lately, I've noticed that PowerShell keeps popping up without any warning. I've checked everything I can think of, and since my computer is pretty old, it doesn't have the latest hardware, but I doubt that's the issue. I'm not the most tech-savvy person either, so I'm a bit confused about what's going on!

If you're looking to check for malware, running a good antivirus program is key. If you haven’t already, try using software like Malwarebytes to do a deep scan. It often catches things that regular antivirus might miss.
It sounds like it might be a malware issue. A lot of info-stealer programs create scheduled tasks that can cause PowerShell scripts to run at intervals, and sometimes they forget to hide the window. You should definitely investigate that possibility.
